Any control deck is going to have 6 cards in hand (Priest, Warrior, Rogue, Druid), mages also have plenty of cards. Any Pro game I've watched they always have more than 6 cards for most of the game. If the meta shifts from Aggro to Control, this card will be in a lot of decks. If it buffs from Don Han'Cho, you have an OTK minion. Windfury.

People compare this to Goblin Sapper, but I think this might be a tad better. One of the problems of the old crazy Goblin was that once he was played, the opponent would start playing cards to be under the hand-size threshold. However, this lady has her effect as battlecry, meaning if she is played meeting the condition, you're enemy instantly suffers the weight of her bike and her bacon in the form of 6 damage.
